Authorities said Spadaccini, a part-time coach at Neumann-Goretti High School, assaulted a 13-year-old in July and August of last year and then gave a 14-year-old student alcohol and a drink spiked with Xanax at a hotel the following month.

Prosecutors said Spadaccini will be sentenced to 12 to 24 years next year under the plea bargain. Defense attorney Tariq Karim El-Shabazz did not immediately return a call seeking comment.
